I have used these on my 4s for a while now, and I have been fairly bummed because the Rotosound website says that they don't make them for 6 stringers. Well, I was looking for strings for my 6er online yesterday and saw this: http://www.juststrings.com/rts-rs776ld.html scam or great find? also, flatwounds seem to have more tension than rounds on my 4s, would there be too much tension on the C string on a 6? One last question, what does "long scale" mean? my 4s are normal 34" scale and take "long scale" rotosounds. my 6 is 35" scale. is that like extra long scale or something?
